Abstract:
From an echocardiographic laboratory database, echocardiographic characteristics of clinical and cardiovascular mortality were compared in patients with restrictive pattern of left ventricular filling (RPLVF) and left ventricular ejection fraction (LVEF) >50% (n = 36), with patients with RPLVF and LVEF <50% (n = 120) and echocardiographic controls (n = 160). Preserved LVEF was found in 21% of the patients with RPLVF. Mortality in patients with RPLVF was worst compared with echocardiographic controls regardless of their underlying LVEF after 2.7 +/- 1 years of follow-up. Patients with RPLVF had distinctive predictors of cardiovascular death, with clinical and echocardiographic characteristics according to their LVEF.
